### AI overview

RF24Gateway is being updated to enable encrypted networking across nRF24, nRF52x, and nRF54x devices. The underlying nrf_to_nrf library provides direct radio communication using Enhanced ShockBurst (ESB), without Bluetooth or Zigbee; its AES/CCM encryption is now enabled for nRF52x and nRF54x. RF24Gateway is intended to let these devices carry TCP/IP and UDP, supporting protocols such as MQTT and HTTP. It requires a Linux host with GPIO and SPI, such as a Raspberry Pi. The code and pull requests are in place, and the author expected a full release within a day or two.

### Source excerpt

TMRh20Projects posted on the Seeed Studio forum about adding encryption to RF24Gateway. The work builds on nrf_to_nrf, a library for direct radio communication on XIAO nRF52840 and nRF54L15 boards. It does not use Bluetooth or Zigbee. It uses the Enhanced ShockBurst (ESB) protocol and direct radio access. The library already included AES/CCM encryption, and that [...]

### AI overview

Relay, a business communications startup, raised $36 million to develop its cloud-hosted smart radio system for frontline workers. The company aims to use AI to capture workers' spoken updates in real time, addressing the loss of operational information that can lead to missed handoffs, rework and delays.

### Source excerpt

The business communications startup Relay Inc. says it's trying to capture "frontline intelligence" for enterprises after raising $36 million in funding, bringing its total amount raised so far to more than $90 million. Today's round was led by the industrial manufacturing giant International Paper Co. and saw participation from the wealth management firm Cerity Partners [...] The post Smart radio startup Relay raises $36M to help businesses capture vital intelligence from frontline workers appeared first on SiliconANGLE.
